During scanning, a module sends the SCANCLK signal to Slot 0 over the SCXIbus TRIG0 line, and Slot 0 sends the SCANCON signal to the modules. In Multiplexed mode, this timing signal reloads the output multiplexer and determines when the SCXI-1140 output is enabled.In Multiplexed or Parallel mode, when the Hold Trigger signal is in Edge-Triggered mode, the SCANCON signal is also counted on the module to determine when to go back into Track mode. Slot 0 contains a module scan list first-in first-out (FIFO) memory chip.
